It’s therefore of particular interest for our healthcare systems that physicians and physiotherapists are able to filter patients with suspected MCL injury prior to referring them to secondary care. The Valgus or Abduction Stress Test is designed to stress the medial collateral ligament. In the 0° position, the test stresses the Pos

VARUS INSTABILITY STRESS TEST FOR TEARS OF THE LATERAL ULNAR COLLATERAL LIGAMENT The elbow joint is very similar to the knee joint. While both joints are hinge joints (when we look at the humeroulnar joint - the radiohumeral joint is a ball-and-socket joint that is restricted by the humeroulnar's shape), they are both stabilized by collateral ligaments. In order to test the lateral ulnar collateral ligament, you are performing the varus instability stress test, similar to the one of the knee. No
